9 Claims. I

This invention relates to apparatus for applying oil to strip and sheet material and the like,

and is more particularly concerned with apparatus for applying uniformly the proper amount of oil to longitudinally moving strip, especially while the strip is being wound on a coiling reel.

It is often necessary or desirable to apply a protective coating of oil to metallic strip or sheet material. For example, customers require that black plate, which is usually sold in coils, be coated with oil. A customary practice is to imm'erse the coils in a bath of oil or pass the strip through a bath of oil. In either procedure, it is difficult, if not impossible, to accurately control the amount of oil applied to the strip. If too much oil is applied, the coils may collapse and if an insuificient quantity of oil is applied, the strip may corrode so that the customer will refuse to accept it and the manufacturer has to scrap the material. Thus, applying the proper amount of oil to strip material such as black plate strip has been difficult and there has been a need for apparatus for applying uniformly the proper amount of oil.

While this invention will be more particularly described in connection with applying oil to strips of black plate while being wound on the reel of a coiler, it is not limited to black plate or to coilers and may be used to apply oil to other materials at other locations.

A primary object of this invention is to provide an improved apparatus for applying the proper amount of oil to strip material and in which the rate of flow and the distribution of oil may be regulated readily and accurately.

Another object of this invention is to provide such an apparatus which may be readily adjusted for applying the proper amount of oil to successive strips of different widths.

A further object of this invention is to provide an apparatus for applying the proper amount of oil to longitudinally moving strip while being coiled on a reel.

A still further object of the present invention is to provide an apparatus which may be used with a strip coiling reel and a coil starting means for applying the proper amount of oil to the strip while being coiled on the reel.

The present invention provides an improved oiling apparatus especially suited for successively which:

applying the proper amount of oil to successive strips of the same and difierent widths whilethe strip is being coiled or wound on a reel. The apparatus includes an oil distributing element, means for supplying oil to this element and supporting means constructed and arranged to permit upward and downward movement of the oil distributing element and to normally urge the oiling element downwardly against the strip under the influence of gravity. Means are provided for varying the effective width of the oil distributing element and for controlling the distribution of the oil. A skid is provided for engaging the coil starting mechanism when this mechanism is moved into the operative position adjacent the reel for starting a coil so that the coil distributing element is automatically moved up out of the way and only a minimum amount of strip is not oiled. The unoiled strip must later be removed. This apparatus has been found to function in a highly satisfactory manner.

These and other objects and advantages will become more apparent from the following detailed description and the accompanying drawings, in

Figure 1 is an elevational view with portions removed to more clearly show the internal structure of an apparatus embodying the principles of the present invention; and,

Figure 2 is an elevational view with portions in section and taken along line 22 of Figure 1,

Referring more particularly to the drawings, the strip material H), which in this particular instance isblack plate, being taken from the final temper rolls of a temper mill, not shown, may be any other strip material such as steel strip, cold rolled steel strip, hot rolled steel strip, tin plate and the like, being taken from the final rolling operation, heat treating operation, or the like. As the black plate I!) is taken from the final temper rolls, it is coiled on power driven, rotating reel ll into coil l2. When the coil [2 has attained the proper size, it is removed and another coil is started. The reel may be of any one of the well known types such as those available on the market.

The coil starting apparatus ll includes a frame l5, belt l6 and a belt tensioning device 11. After a coil has been completed and removed from reel I I, the coil starting apparatus is moved to the left to an operative position adjacent reel II. In this position, the belt 18 extends nearly around the reel II and the leading end of the strip can be inserted between the belt and reel and the reel rotated to start a new coll. After the coil is started, the coil starting means I! ismoved toward the right to the inoperative position shown in the drawings.

While this invention is not limited to any particular type of reel and coil starting mechanism, they may be of the general type shown in the United States Patent No. 2,322,784, issued June 29, 1943 to C. J. Klein. 1

The oil distributing brush it includes a wooden back I9 in which are mounted oil spreading bristles 20. The brush I8 extends transversely of strip 10 and is as long as the widest strip to be oiled. The oil is supplied to the brush It at spaced points throughout its length by a plurality of separate tubes 2|, each extending through the wooden back l9 as shown more clearly in Figure 2. Each oil suppl tube is screwed into one side of a pet cock 22 which is connected through a nipple 23 to a corresponding T or elbow pipe connection 2|. All or the pipe connections 24 are-connected in line by nipples 25 to a T connection 26 so that the oil supplied to connection 26 flows to brush id at a plurality of spaced points. The amount of oil flowing through each tube 2 I can be regulated by adjusting the corresponding valve 22 or can be shut oil when desirable. The T joint 2% is connected through unions 28, elbows 29, elbows as and valve 36 and pressure gauge 32 to a T connection 33. The valve 3i can be adjusted to vary the total amount of oil or closed to entirely shut oii the flow of oil. The connection 33 is connected to the main oil supply pipe 36 which in turn is connected through elbow 35, pipe as, swivel connection 31 and pipe 38 to a source of oil. Thus, oil is supplied to. the brush it at spaced points therealong by a plurality of passage containing members, each associated with a. valve for individually controlling and regulating the flow of oil therethrough to vary the effective width of the oil distributing brush i8 and to vary the amount of oil flowing to the brush and to control the distribution of the oil along the brush.

The oil supply pipes and swivel connection 31 also support the brush I8 for movement in an arc downwardly toward and upwardly away from an operative position adjacent strip III as it is being longitudinally wound on the reel II. The brush It is normally urged against strip I0 under the influence of gravity and can move upwardly during winding of the coil I2 against the influence of gravity to compensate for the rising level or the strip as the diameter of the coil I2 increases.

A skid 40 is fastened to oil supply pipe 34 in position so that when the coil starting mechanism is moved toward reel ll to an operative position adjacent the reel ior starting a new coil, the upper portion ll of mechanism i4 strikes the skid 40 and raises brush l8 away from the reel I I and the strip to an inoperative position against the influence of gravity. After the new coil has been started, the coil starting mechanism is moved away from the reel II to an inoperative position and the brush 18 drops down against the strip Ill so that only a very small amount of the starting end of the strip is not oiled. This reduces the amount of scrap.

If the strip to be coiled is narrower or wider than the previous strip, the efiective length of the brush is decreased or increased by closing or opening the end valves 22 and the other valves 22 may be adjusted, if desirable, to control distribution of the oil; Either valves 22 or valve 3| may be adjusted to vary the total amount of oil applied to the new strip. Once valves 22 are adjusted for the proper distribution ofthe oil, the total flow may be readily adjusted by means of valve 3|. Before starting a coil, the coil starting mechanism It is moved toward the left until the belt l6 extends nearly around the reel II. The upper portion ll of mechanism It engages skid MI and swings the brush l8 up and away from the reel. After the coil starting mechanism is in position, the leading end of the strip is inserted between reel II and belt I6 and reel ll is turned through at least one revolution. The belt I8 causes the strip to wrap around reel I I to start a new coil I2. The mechanism I4 is then moved out of the way and the brush automatically moves downwardly against the strip. As the reel is rotated to coil the strip, the brush and strip are relatively moved in a direction extending longitudinally of the strip to apply the proper amount of oil along the strip and as the level oi! the strip rises due to the increasing size of the coil, the brush automatically moves upwardly.

Having described my invention in detail, it is obvious that certain changes can be made therein without departing from the spirit or scope of my invention. For example, the oil supplying means and the supporting means for the brush may be separate and oil distributing elements other than brushes may be used.
